Shotgun and spade would have been a more permanent fix.

Welcome I am interested to know why you looked into a GSHP? Three things, with a 'system' type boiler, which a HP is, DHW is stored in a cylinder, ready for use, so no waiting, and you can get very good flow rates. An UFH installation requires extra insulation under it, more than building regulations suggest. This is because the floor will be at 35 to 40°Cm rather than about 18°C, but the ground will be at the same temperature ~10°C. It is the temperature difference that is important. Finally, it does not matter what temperature the heating system works at, the energy needed to heat a building to the desired temperature will be the same. Power, Energy and Temperature are different things. Reducing thermal losses means you can use a smaller system, most heating systems are sized for DHW demand and not space heating, but an ASHP is designed to be a little larger than your peak power demand. This keeps the Coefficient of Performance (CoP) in a more efficient place. Then there is the manner in which they are used, they are kept on, chugging away, rather than blast out heat, turn off for a while, then blast again. Modern ASHP, if designed and installed correctly, are not expensive to buy or run, nor are they noisy.

Probably, and for DHW usage. The loft is a strange place to install an ASHP, or do you just mean the buffer and cylinder, maybe a pump as well, are up there.

UV curing acrylic is used to repair windscreens. This is mainly because it adheres to the acrylic film that makes up the laminate. It has a slightly different refractive index to glass, so can be quite visible when looked at from an angle. Polishing anything properly is long and painful, you have to polish much more than you ever imagine. If your glass is covered by insurance, a small child throwing marbles at it can cause real damage. But depending on the size, maybe @pocster can help.

How traditional.

Only because I told her to say that to you.

Yes, but we don't polish ours. I guess Cornwall is too far for the Zoe to get to. Still the mountain men on Exmoor will keep you warm.

That is because you were in Devon you (expletive deleted)ing halfwit. This is Cornwall, we have palm trees and pampas grass.

Cost difference between gas boiler and ASHP
SteamyTea replied to Moonshine's topic in General Plumbing
So probably comparing a basic combination boiler with a proper HP installation. Why don't they compare a system boiler to a non MCS setup. -
Too late, already been told off and had a post deleted. So much for bringing light relief to these troubled time.

Cost difference between gas boiler and ASHP
SteamyTea replied to Moonshine's topic in General Plumbing
Did that include digging up an existing floor, insulating and recasting? And did he cost in connecting to the gas main if it is further away than the free connection. Was going to visit £20,000 to connect my house. One of those things that cannot really be compared purely in hardware prices. -
Single room MVHR. And internet disconnect.

Porcelain & Chicken Poo
SteamyTea replied to canalsiderenovation's topic in Landscaping, Decking & Patios
Look at this. https://www.britishceramictile.com/how-to-tile/ceramic-vs-porcelain-tiles Seems that the glaze is a separate thing. -
Read up about it here. https://en.wikipedia.org/wiki/Thermal_radiation The calculate that it isn't worth the bother as the temperature differences are too small. Thinking about it as visible light is not how it works, we can't see sound and radio waves, but we can reflect, bend and focus them. The smaller the gap between the radiative and adsorption surfaced the more energy transferred. Conduction is only radiative transfer, but at the scale of electrons turning into photons.

Solar PV + Tesla Powerwall (or storage battery)
SteamyTea replied to magutosh's topic in Photovoltaics (PV)
At 11p/kWh, that is about the same as my E7 night rate and about 11p saving over my day rate. Trouble is I only use between 1 and 2 kWh during the day. So £9000 / £0.11 = 81,818 kWh 81,818 kWh / 2 = 40,909 days 40,909 days / 365 days = 112 years The price needs to come down tenfold. -
MVHR- real world performance?
SteamyTea replied to DragsterDriver's topic in Mechanical Ventilation with Heat Recovery (MVHR)
Steam is condensate and will not disappear, it will coalesce on surfaces, just like vapour (which is a mixture of gas and condensate) will if the surface is colder than the transition temperature. -
MVHR- real world performance?
SteamyTea replied to DragsterDriver's topic in Mechanical Ventilation with Heat Recovery (MVHR)
Eh? You need to clarify that a lot more. -
Few more leaks and you can charge plumber's rates.

Get a flexible.
